I couldnt clearly understand what kind of help you are looking for exactly.

Do you need somebody for the scripting part as your comrade left the project?

Or do you need help to balance the battle system to make it more appealing and fun?

Or do you look for ideas of alternative battle systems since you ran into a couple of flaws with yours?

If you could clear this up a little i am sure there will be somebody around to help you out.
